Satellite proposed to send solar power to Earth

B – Artemis Innovation Management Solutions has been given some seed money by NASA to look deeper into a project the company first proposed last summer; namely, building a satellite that could collect energy from the sun and beam it back down to Earth to add to the electrical grid. Building such a satellite has been bantered about for several decades by various groups and scientists, but until now, no one had come up with a design that would work given all the constraints of the time. But now, an idea proposed by longtime NASA engineer John Mankins, now with Artemis, has clearly created enough interest within NASA that some money to investigate the idea is being offered.[/b]
The project called Solar Power Satellite via Arbitrarily Large PHased Array (SPS-ALPHA) would make use of thin filmed mirrors to reduce weight which would be curved to take maximum advantage of the sunlight it receives. Also, the satellite would sit far enough away from planet Earth so that it would never be in the dark, allowing for a constant stream of microwaves.
The initial seed money is to carry out a feasibility and proof of concept study. If NASA likes what it sees, the next step would likely be the construction of a pared down, cheaper version of the project working from a near Earth orbit. If that works out as planned, than the full scale satellite would be built and sent up, perhaps becoming the game changing solution to energy production that so many researchers the world over have been looking for.
